Application November s,1949,4se'ria1 no, mais; ,A I "setlists".` (01.259481) I This inventionrelates to an improved electric motor driven freezer of the type adapted`to be used inr a domestic mechanical refrigerator to freeze confectionssuch asice cream,lthe primary object of the invention being to provide amore efficient and practical device of this kind composed of a minimumnumber of simple parts which canl be easily assembled and disassembledfor cleaning or` repairs, and capableiofbeing made in an attractive andserviceable format relatively low cost. Y

`Other important objects and advantageous features ofthe inventionwillbe apparent from the following description and the accompanyingdrawings, wherein, merelyfor purposes of illustration, a specificembodiment ofthe invenl tion is set forth in details lIn the drawings:

Figure 1 is a top plan view;

Figure 2 is a side elevation;

Figure 3 `is a right-hand end elevation of Fig- 4 I Figure i` is avertical longitudinal section taken on the` line 4-4 of Figure 3'; 1

`Figure 5 is aplan view of the drum container removed from the frame orbase 'and partly in section, and with a capcover removed and shown indotted lines; I l i i I Figure 6 `is a transverse vertical section takenon theline 6 6 of Figure 2; Referring in detail to the drawings, whereinlike numerals designate like parts-throughout the several views, theillustrated device comprises a base or frame 'I `in the general form ofa rectangular refrigerator tray hav-inga bottom 8, longitudinal sidewalls 9,'9, and an end wall IU, the upper edges of the side walls 9 andside walls I being on the same level and provided with a bead II. Thetray 'I has another endiwall I2 which hasa semicircular cutout portionI3. At each side of the end wall I2 the side walls 9 have inwardlyprojecting flanges "I4" at their upper edges. w 1

A motor support plate or base|5 has ears I6 at the opposite ends to restupon the flanges I4 and wing bolts II traverse the `ears and flanges tosecure the motor base removably in place; The motor base I is concavedintermediate' its ends to fit the cutout portion I 3 andv provide aportion .I8 secured to and contoured nto conform to the under side ofthe casing of a small electric motor I9 having a squared shaft end 2Dprojecting from the motor casing tov/ard the opposite end of the trayand parallel to the bottom 8 thereof, as

am :e Een? i' ne @is i! estende from the motor I9 for connection to asuitable source of current preferably an outlet vwithin the refrigerator(not shown). The motor shaft `end 2B is axially aligned with a bearinghole`22 provided in the upper part of thetray endl wall IIl. Thecontainer drum, generally designated 23, comprisesa hollow cylinder 24having an` end closure 25 having a centered recess 26 opening yat itsinner side. The outside of the cylinder 24 adjacent the end closure 25is threaded, as'indicated at 2l, to provide for removableattachrnentthere-V to of the cap 28 which has a centered pintle 29 toproject through and turn in the bearing hole 22 in the tray end Wall I0when the drum 23 is in place in the tray 1. When the drum is removedfrom the tray l, as on completion of a confection freezing operation,the cap 28 can be removed from the closed end of the drumandythreaded onthe external threads 38 on the open opposite end 31 of the cylinder 24,the open endj 3'I'` being closed during operation of the device by thecover cap 32. i

The cover cap 32 has a central boss 33 having a squared socket 34 intowhich the squared motor shaft end 2B is fitted to support the adjacentend of the drum 23 and form a drive connection between the motor and thedrum. The shaft end 28 is optionally permanently or removably fitted inthe socket 34. The boss 33 has another socke 35 in the inner end.

An agitator or paddle assembly, generally designated 36, is not drivenby the motorIS, but fits snugly and removably Within the drum cylinder24. The paddle assembly 3E comprisesv a rectangular frame composed oflongitudinal side members 3l, 31 connected at their ends by end members38, 38, each having an outwardly projecting pin 39 centered thereon forengagingin the recess 25 in the drum end closure 25 and in the socket 35in the cover cap boss 33, whereby the assembly is secured againstendwise movement in the cylinder and the paddle frame and members 38arespaced inwardly from the ends of the cylinder 24. rThe paddle assembly35 furv ther comprises a longitudinally paddle: bar 39 connected to andextending between theV midpoints of the end members 38. Extending fromthe bar 39 in Vthe plane of the end `members38 are spaced pairs ofdiametrically -opposedshort paddleflngers 40,49 and apair ofintermediate longer paddle ngers 4I','4I.` VThe' fluid from which thedesired confection is frozen beats against the paddle assembly 36 as thedrum 23 is rotated, whereby the fluid is adequately agiamigas atoriceicube freezing; tray, can be readilyo sub.-
